EDVARD RYAN AND OSCAR JOHNSON, OF CLINTON, IOVA.

LOCOMOTIVE-TENDER.

SPECIFICATION formingpart of Letters Patent No. 675,795, dated June 4,1901. Application filed August 28, 1900. Serial No. 28,233 (N0 model- Toali whom it may concern:

Be it known that we, EDWARD RYAN and OSCAR JOHNSON, citizens of theUnited States, residingat Clinton, in the county of Clinton and State ofIowa, have invented certain new and useful Improvements inLocomotive-Tenders; and we do declare the following to bea full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters ofreference marked thereon, which form a part of this specification.

This invention relates to improvements in locomotive-tenders, the objectof the invention being to provide means which can be readily operatedfrom the forward end of the tender, the cabin of the engine, or at anyother suitable or desired point for agitating the coal in the coal-pitor moving the same forward, so that it can be readily reached by theireman without having to enter the tender to agitate the coal or movethe same forward.

Locomotive-tenders as usually constructed are provided with a water tankor tanks and a coal-pit surrounded by the tank or tanks, except at theforward end of the tender,which is usually provided with a gate or door,and it often happens that the coal, being used from the forward end,clogs in the rear end of the pit or is so far back that it is ditlicultfor the fireman to reach the same with his shovel, and it thus becomesnecessary for him to enter the pit and loosen the coal or move the sameforward, where it can be easily reached from the forward end of thetender.

It is one object of our invention to provide means for obviating thislabor on the part of the fireman andwhich can be readily operated fromany desired point to loosen the coal or move the same forward in thepit.

A further object is to provide such means with fluid-pressure-operatingmeans controllable within the engine-eab or at any other desired point.

A further object of the invention is to provide a tender of the' usualconstruction with a movable back or side for the coal-pit and means formoving the said part to loosen the coal or move the same forward in thepit.

A further object of the invention is to provide a movable side or backfor the coal-pit and provide means to prevent the coal getting behind orunder the back or side to prevent its proper operation.

A further object of the invention is to provide a locomotive-tender withsimple and effective means for agitating,loosening,or moving the coal inthe pit.

With such and other objects in view the invention is embodied in thenovel parts, arrangement, and combinations of parts hereinafterdescribed, and particularly set forth in the claims.

In the accompanying drawings is illustrated a practical embodiment ofthe invention; but it is to be understood that the invention is not tobe limited in its useful application to the construction which for thesake of illustration is there delineated.

In the drawings, Figure 1 is a plan view of a locomotive-tenderprovidedwith the invention. Fig. 2 is a longitudinal sectional viewthrough the tender shown in Fig. 1, showing in dotted lines and fulllines the diiferent positions of the coal moving or loosening means.

In the drawings we have shown only the body of a tender, which isconveniently of the usual known construction and is provided with theside and rear water-tanks or substantially U-shaped tank, (indicated atA.) Between these tanks or the space formed between the sides of thetanks is the coal-pit B, as is usual in the common construction oftenders, and it is believed that a detailed description of thetender-body and tanks is not necessary to an understanding of thisinvention.

C indicates a gate or door at the forward end of the tender between theparts of the tank A for the purpose of preventing the escape ofthe coalfrom the pit. This gate is such as is usually employed.

E indicates a movable part, back, or side of the coal-pit which by amovement thereof is adapted to agitate, loosen, or move the coal in thepit. Preferably this part is fashioned as a supplemental back or sidefor the coalpit and has the inclined body F extending down into thecoal-pit and hinged, as by hinges j', in the bottom of the pit. Securedto the body part F are side flanges G, fashioned to conform to thevertical lower side IOO portion and upper inclined side portion of theparts of the Water-tank A. The parts F and G are preferably' providedwith vertical flanges F and G, lying against the sides of the body ofthe tender above the Watertank and indicated at H. It will thus be seenthat the movable means or part E is substantially the shape of the rearportion of the coal-pit and rests upon the inclined back J and sides ofthe coal-pit. By a movement of this part E on its hinges the coal whichrests thereon is moved to loosen the same or move the same forward, andfor the purpose of moving or oscillating the part E the same is shown asbeing provided with a piston-rod K, hinged in any convenient or desiredmanner to the part E and provided at its end with a piston 7;, Workingin a cylinder L, located beneath the part E. The cylinder is shown asbeing mounted within the rear portion of the water-tank. This cylinderhas connected to it, conveniently at the lower end thereof, asupply-pipe M for a motive {luid-s uch as water, steam, or air-and thepipe M may be connected bya suitable IleXible hose N or otherwise to anysource of fluid-pressure, such as a steam-pump or the air-brake systemor reservoir of the locomotive. Suitable means (not shown) is providedfor controlling the admission and exhaust of the fluid motive medium tothe cylinder L to control at will the operation of the piston therein tooseillate or agitate the part E.

Itis apparent that when the part F is moved on its hinges the side[langes G move up and away from the underlying inclined faces oil thewater-tank, and if not provided with means to prevent the same the coalin the tank is apt to work under the side flanges G and prevent theproper operation of the part E. To prevent this, each flange G isprovided at its forward edge with a hinged wing O, hinged, as by meansof hinges o, to the flanges G. 'lhe forward edges of the wings O in themovement of the part E rest and slide on the inclined faces of thewater-tank, thus always effectually closing the spaces between the wingsor flanges G and the inclined faces of the water-tank.

It will be understood that the controlling means for the motive fluid tothe cylinder L can be located and operated :from any desired point-as,for instance, the cab of the engine. It is not, however, believednecessary to particularly describe or illustrate any particular meansfor the controlling of the motive fluid.

Having thus described the invention, what is claimed is- 1. Alocomotive-tender having a coal-pit and an opening at the forward end topermit access to the coal, and provided with movable means for looseningor moving the coal therein, and means for operating said movable means,substantially as described.

2. A locomotive-tender having a coal-pit and an opening at the forwardend to permit access to the coal, and provided with movable meanslocated in the coal-pit thereof for loosening or moving the coaltherein, and fluid-operated means for moving said movable means,substantially as described.

3. The combination with a tender, of movable means for loosening andmoving the coal therein, and means controllable from without the tenderfor operating said movable means, substantially as described.

4. The combination with a locomotive-tender, of movable means located inthe coalpit thereof for loosening and moving the coal, andfluid-pressure-operated means controllable from without the tender foroperating said movable means, substantially as described.

5. The combination with a locomotive-tender of a movable part, locatedin the coal-pit thereof, for the purpose described, constituting aportion of the wall of the coal-pit, and means for operating saidmovable part, substantially as described.

(i. The combination with a loconiotive-tender, of a movable back orside, located in the coal-pit thereof, and fluid-pressure-operated meansfor operating said movable back or side, substantially as described.

7. The combination with a locomotive-tender, of a movable part locatedin the coal-pit thereof, a piston connected to said part, a cylinder inwhich said piston operates, and means for supplying said cylinder withiluidpressure and controlling the admission and exhaust thereof to andfrom the cylinder,sub stantially as described.

S. The combination with a locomotive-tender, of a side or back hinged inthe coal-pit thereof, a piston connected to said hinged side or back, acylinder in which said piston operates, and means for supplying saidcylinder with fluid-pressure, for operating the piston, substantially asdescribed.

9. The combination with a locomotive-tender, of a part F hinged to thebottom of the coal-pit thereof,and having side wings,ineans for movingsaid part,and wings hinged t0 said side wings, substantially asdescribed.

lO. The combination wi th a locomotive-tender having a water tank ortanks at the side thereof, and a coal-pit between the same having aninclined back, of a movable part comprising an inclined back F hinged tothe bottom of said coal-pit and having inclined side flanges or wingsresting on inclined faces of said coal-pit, means for moving said part,and wings hinged to said inclined side flanges or wings, and adaptedwhen the part is moved to rest and slide on the inclined faces of saidcoal-pit, substantially as described.

In testimony whereof we affix our signatures in presence of twowitnesses.
